The Multiquip 0482 is a genuine OEM O-Ring Mechanical Seal Housing designed for Multiquip QP-series trash pumps, QP-series centrifugal pumps, and MQ62T-series trash pumps. As a factory-sourced component, part 0482 delivers the exact material compound, cross-section diameter, and compression rating required to maintain a leak-free seal at the mechanical seal housing interface. This O-ring is confirmed to fit a wide range of models including MQ62TDD, MQ62TK, QP3TH, QP4TH, QP2TH, QP3TK, QP4TK, QP4TB, QP3TB, QP3TS, QP3TZ, QP4TZ, QP2TK, QP2TB, QP2TZ, QP3THX, QP4TKT, QP303B, QP303H, QP402H, QP15HP, QPT305SLT, QPT205SLT, QP305SLT, and QP205SLT — making it a versatile service part for mixed pump fleets.
Key Features
- OEM-Grade Elastomer Compound — Manufactured to the exact material specification required for the mechanical seal housing, ensuring correct compression and chemical compatibility with pump fluids.
- Drop-In Housing Fit — Sized to the original groove dimensions of the mechanical seal housing, seating correctly without stretching, trimming, or modification.
- Broad Pump Fleet Coverage — A single part number covers MQ62T trash pump models, QP-series trash pumps, and QP-series centrifugal and dewatering pumps, simplifying parts inventory across your fleet.
- Leak Prevention at the Seal Interface — A correctly seated O-ring at the mechanical seal housing prevents fluid bypass around the seal, protecting the pump casing and maintaining prime and discharge pressure.
- Fuel and Fluid Resistance — The O-ring material is suited to sustained contact with water and pump media handled by both trash and centrifugal pump configurations in this family.
The O-ring at the mechanical seal housing forms a static seal between the mechanical seal cartridge and the pump volute or housing bore. Its job is to prevent pumped fluid from bypassing the mechanical seal and escaping along the outside of the seal housing. When this O-ring deteriorates — through compression set, cracking, or chemical degradation — the pump will weep or leak around the seal area even if the mechanical seal faces themselves are in good condition. Replacing the O-ring during any mechanical seal service is standard practice and is the lowest-cost step to ensuring a fully leak-free pump after reassembly.
